The invention relates to improvements in burner-outlets, a support for fuel which sup port in inclined rearwardly and upwardly away from above the burner outlets, radiants carried by said support so as to present a surface inclined similarly to the support, an artificial coke-blanket arranged over said surface, an inclined tray forming an extension of the support beyond the radiants loose artificial coke on said tray, and means which secure both the artificial coke-blanket and inclined tray to the top of the support for 11181.

The words artificial fuel used throughout the specification and claim denote materials which when placed in a gas-flame emit radiant heat without combustion of the materials. The words artificial coke-blanket throughout the specification and claim denote a plurality of pieces of artificial fuel so secured together as to form a mat-like structure, which artificial fuelis so manufactured as to have the appearance of coke.

It will be appreciated that a gas-fire such as described above may be built into different forms of framework so as to representvarious grates, such as a dog-grate or a basketgrate, and thus may easily be installed in fireplaces constructed for such grates.

A further feature of the invention consists in so forming said support that it locates and carries above it the said radiants and a backing, and carries beneath it a gas-burner and ejector-nozzle. The said gas-burner is preferably secured to the said plate by three attachments. v

Other features of the invention will be apparent from the claim and from the following description of one form of gas-fire ace-ording to this invention.

Reference is made to the accompanying drawings, in which t Figure 1 is a front elevation of a gas-fire with the trivet removed and having the appearance of a basket-grate;

I are located above the burner-nozales by means Figure 2 is a section on theline 22 of Figure 1, and 1 Figure 3 is a front perspective viewof a gas-fire. I Y

The frame of the gas-fire comprises two side-plates 1, 1 to which are' securedlbackplates 2, 3 and a front plate 4. refuel-support 5'rests on and-is secured to lugs (not shown) cast integral with the said side plates.

Thefuel-support is provided on its under side toward each endthereof with a socket '6 and at the centre of lt-SfOYWEIICl edge with a 8 having a number of burner-outlets 9 is car- 'ried beneath the fuel-support by means of lugs-1O formed on the burner, which lugs rest in the said socket 6. The burner is also provided with a -,forwardly extending lug 11 which is secured to the before-mentioned lug fuel-support is arranged to. carry the firebrick-backing 14:, side br cks 15 and the lower radiants 16. The radiants' ar'e tubular and of projections 17 formed integral with the fuel-support. The lower back-plate '2 is arranged to extend vertically up to the level "of the burners, and the upper back-plate 3 is inforwardly-projecting lug 7. The gas-burner clined to the vertical, so that the fire-brickback and radiants which it locates are inclined rearwardly and upwardly away from the burner-outlets. An upper radiant 18 is supported by the lower radiant 16 and eX-sa tends to the top of the fire-brick backing. An artificial coke-blanket 19 is suspended from the top of the upper back-plate 3 in a manner hereinafter described. Thecoke-blanket comprises a plurality of pieces of artificial fuel 20 which are threaded together ,on lengths of iron wire 21. The mat is secured in position by means of links 22 which are arranged to hook on to the iron wire at the top of the mat and also on to a rod 23 which is carried by a metal strip 24 secured to the backing 3 by set-screws 25.

Secured also to the top of the backing 3 is a tray 26 which is arranged to extend upwardly away from the backing and forms a? continuation of the front sloping surface of the radiants. Loose pieces of artificial fuel 27 are located on the said tray. The said tray may be cut so that its contour may fit snugly into an existing fireplace. The tray and the strip 24 are secured to the backing by the same set-screws 25. The front plate 4 extends upwardly in front of the burners and is curved outwardly so as to form a gap between it and the lower radiants16, The lower extremity of the artificiahcoke-blanket is located'in said gap, as is best seen in Figure 2,

V and the top portion of the front plate thus continuation of forms a guard. "A trivet 28 is arranged to cover the burner.

' It Will be appreciated that in the construction above described the fuel-support serves to support and locate the chief elements of the gas-fire in relation to one another, that is tosay it locates the fire-brick-backing, side 7 bricks, radiants, the gas-burner and injectornozzle.. Further,the burner may readily be- I I claim :V p

. A gas fire of the class specified, comprising a framework, a burner with a series of gas nozzles extending longitudinally in-thelower part of the framework, a plurality of hollow radiants' supported to extend upwardly and rearwardly from theburner nozzles, a backplate supporting said radiants, the upper edge of said backplate terminating in substantially the sameplane as the upper surfaceof the radiants, a blanket of interconnected radiant lumps overlying the hollow radiants and susremoved by releasing the set screws 7.

pended from said upper edge of the back- 1 plate, an extension plate inclined upwardly and rearwarclly from the backplate, said extension plate being adaptable to fillthe gap in a fireplace above thegas fire, and a'supplemental system of radiant lumps on said ex tension plate and constituting a substantial the blanket overlying the radiants.

, In testimony whereof I aflix my signature.
